Document Summary
Key outcomes: people can permanently adjust their neuroanatomy, people can make themselves much happier and emotionally stable than previously believed and people can affect even low-level processes. Our brains" connections are refined and retuned with every experience of our lives. the brain is constantly evolving. Plasticity is amazing but the limits are unknown. Only recently have we begun to appreciate our brains" incredible plasticity or ability to change. Current huge questions concern the outer limits to which people can learn to manipulate their own neural functioning and the benefits gained. Practical questions concern how to create a more brain-healthy society. Brain areas can even recruit systems normally devoted to other tasks. Example: cut off a finger: that part of the sensory cortex will start to receive signals from the other fingers: enhanced sensitivity. Example: if blind, the sensory cortex corresponding to the braille-reading finger expands; sense of touch starts to get processed by the visual cortex.
